    Truth about PDK

    Now we know why it REALLY is so late....got the info from fchat,

    The DSG in the VW is Porsche's system already. Porsche invented clutchless shifts 25 years ago and licensed the technology for 15 years to VW- which ends this year. That's why 08 Porsche's will come with PDK.
    The Porsche system is the quickest shifting.

    Re: Truth about PDK

    I doubt a license to VW was exclusive. The reason PAG has not released it yet is because they need a system that handles high torque. BTW... PDK is not clutch-less. It has 2 clutches, it just does not have a clutch pedal, as you could not have the dexterity to operate 2 clutches.

    Exactly. Audi also has that problem. VAGs current DSG tranny sitting inside the VW Golf, Audi A3 and Audi TT can't handle a lot of torque. That is the reason why it is not offered in cars like the R8, RS4 and Audi S6.

    Re: Truth about PDK

    but how come Bugatti use 7G - DSG .i guess there is no problem with High torque..

    I've asked myself that question and can unfortunately not give you the proper full explanation. But apparently the DSG in the VW Golf isn't not the same as the one in the Veyron. The DSG sitting in the Veyron is different and heavily tailored for car and VAG had a tough time making it function properly, hence the long R&D development time for the Veyron.

    The DSG in the Veyron is probably too expensive to put inside a Porsche or an Audi and further more it wasn't design by the same company which developed the DSG used by VW and Audi, though both firm do have the same parent company.

    Veyron DSG



    VW/Audi/Seat DSG

    Yes it can; the Veyron DSG is a special build to handle that torque.

    Unfortuntaly, it has some drawback: it accounts for about 50k USD if I am not mistaken. Maybe this limits the applicability in VW, Audi and also Porsche cars...

    yah

    Re: Truth about PDK

    I thought the Veyron DSG was just far too heavy. Fine if you have 1001bhp to cart it around...

    Re: Truth about PDK

    so is it confirm on 08 build models with PDK as an option??

    No, it's a *maybe* on the 997 Carrera facelift around the end of 2008. More likey will be for the Panamera release.

    Re: Truth about PDK

    VW's DSG is designed for transverse mounted engines, it won't work on the Turbo, plus it's only a light duty and the Turbo will make mince meat of it.

    Veyron's is a a correct design for the longitudinal mounted Porsche engines but it's far too big, heavy, expensive and overbuild for Porsche's needs.

    Porsche needs one that can handle 500-600lb torque, and it needs to be compact.

    I think the PDK appearing in the Panamera first is a good possibility, they may actually do what Maserati does with the quattroporte, offering the PDK and the tip and no manual gearbox.

    PDK is a natural evolution for the manual transmission and I would not be surprised at all if Porsche replaces the manual with PDK and keep the tip version. This will no doubt offends the hardcore group of owners like what they did with the air-cooled engines. But with time these people will see the light and realize no matter how good, quick their shifts are, they will never match the PDK in speed and smoothness.

    What would be the point in offering both, Tiptronic and PDK?

    As far as I understand, the Tip is more expensive to build then a DSG; even if Porsche will surely charge more for it after its introduction. Thus, what would be added value for Porsche to offer the Tip in the future?
    The manual will surely be offered in the future as you cannot serve all markets with only Tip/PDK.

    Already told by Porsche that PDK will replace Tip, not manual.

    Re: Truth about PDK

    Tip + PDK seems like 'more of the same' no?
    PDK can work in full auto mode, ain't this what tip buyers go after?

    Absolutely correct. "PDK" replaces Tiptronic, not manual. Porsche can finally end the "ordeal" to use a major drivetrain part from one of their toughest competitors.

    Correct. I have driven the VW GTI with DSG and in auto mode it offer the same experience as an automatic. The gear changes are amazingly smooth and that also goes for the transmission in manual mode. With that being said PDK will make tiptronic obsolete. Manual and PDK will the Porsche's offerings int he future.

    So RC are you agreeing with the OP that PAG was licensed restricted until now to introduce PDK?

    I assume he meant the tiptronic supplied by DaimlerChrysler.

    Re: Truth about PDK

    just to add some info Veyron's gearbox was made by Ricardo. They're specialists in racing transmissions, specially of le mans prototypes (like audis!!).

    Re: Truth about PDK

    Would Porsche really offer the PDK quietly in mid cycle on the 997? It doesn't seem to be an option on '08 orders. Can you imagine taking delivery on the Tip and having the PDK show up a few months later?

    Just developed by Ricardo or developed AND made by Ricardo?

    Re: Truth about PDK

    The current tip is from MB, the same 5-speed one in the AMG 55 cars.

    Re: Truth about PDK

    Been waiting for this since the 997 came out and am feeling really disappointed as it doesn't look like it'll be ready anytime soon. Porsche really fell behind on this. Now I'm probably going to have to look for alternatives. F-car?

    Why mid cycle?
    MY08 runs short only until March/April.
    MY09 with the facelift starts in spring 2008. As with the Cayenne update this year.

    Re: Truth about PDK

    - 997 Tip is coming from MB
    - Cayenne Tip is from Aisin
    - Boxster/Cayman I don't know but I suspect it is from MB as well

    Re: Truth about PDK

    Now I'm confused. My dealer told me I'd have his last allocation for an '08 turbo coupe - we're placing the order in April. Does that mean my car will really be an '09?

    Re: Truth about PDK

    It depends of its built date...

    Before July 31-08 it will be a MY-08
    After Aug 1-08 it will be a MY-09

    A bunch of us went the AMV8 route while waiting for something more exciting from Porsche. New F cars are not an option for non repeat buyers in the US.

    Depends on the country, US doesn't have the same regulations.

    Repeated rumours are that only the Carrera gets a facelift and not the TT. As such, I would expect that the TT will have a normal MY08 until August 2008 and just the "normal" 997 variants will have a MY09 starting in spring 2008.

    Re: Truth about PDK

    That would make me think that Porsche will not be offering the PDK for non-turbo 997 variants in the '09 MY. It would seem strange for Porsche to introduce it on '09 997s and not have it for the '08 997tt that would carry through to August. Of course they could add the option for mid-year turbos, but it seems more likely that it will show up for the '10 or '11 models. This is purely speculation, though.
